Question about 2008 Hummer H2 SUT
Try to locate the relay center, usually located under the hood or sometimes in the trunk. In your case, possibly an access panel in the back. Once you locate the relay center, look at the inside of the cover that you removed. There is usually a diagram of the relays and what they are used for.
1. Look for the relay that has any thing to do with the windows.
2. Locate another relay in the same panel that has the same part number.
3. Switch that relay with the one for the windows.
4. Try to operate the window.
If the window now operates, then replace the relay as soon as possible. If it doesn't, then look for another fuse panel. They can be in a number of different locations, in the glove box, under the dash, inside the kick panels just in front of the doors and in the trunk. Try the same thing with the fuses if you find a bad one. I hope this information has been helpful. Thank you for using Fixya.com.
